How long does antimicrobial coating last?

Since the cured antimicrobial is non-volatile, insoluble, and non-leaching, the treatment should continue to be active for up to 60 days, and in many instances we have seen efficacy maintained in lesser trafficked areas for considerably longer. A treated surface’s life span depends on a number of factors, not least of which is surface preparation. Treating a dirty or unstable surface decreases the effectiveness of the antimicrobial. Abrasive or caustic (pH 9.0) cleaners can shorten the effective life of a treated surface. Our professional applicators have seen long term effectiveness for the life of the substrate under normal cleaning conditions.
